Bridges

High performance protective coatings

With many modern bridges having a lifespan of up to 120 years, the performance of the protective coating used can be a critical factor. In addition, the requirement to reduce the number of repainting cycles has become significant in the overall evaluation of the whole life costs of such structures.

PPG is a world leader in the specification and supply of fit-for-purpose coatings for bridges. On well-designed bridges, our high-performance, environmentally preferred coating systems can be expected to last in excess of 25 years before recoating is required.

Choosing a fit-for-purpose bridge coating often requires a wider understanding and consideration of a range of factors including the condition of the structure, possible mechanical or chemical stress and UV exposure. Our experienced technical support team is always available to provide professional advice and to ensure that the correct coating is specified and applied.

Widely used PPG coatings products that are often specified for use on bridges include:

PPG PSX 700 is a unique system that uses patented engineered siloxane components to deliver the excellent adhesion, toughness, corrosion- and chemical resistance of epoxy siloxane. It also delivers proven cost savings by removing the need to use a traditional mid-coat epoxy.
